What is drilling fluid and why you need it?
Drilling mud, also called drilling fluid is a heavy, viscous fluid mixture that is used in oil and gas drilling operations to carry rock cuttings to the surface and also to lubricate and cool the drill bit.
The drilling mud, by hydrostatic pressure, also helps prevent the collapse of unstable strata into the borehole and the intrusion of water from water-bearing strata that may be encountered.
Drilling muds are traditionally based on water or naturally occurring brines. Many muds are oil-based, using direct products of petroleum refining such as diesel oil or mineral oil as the fluid matrix.
In general, different muds can be used specifically for the peculiar wells and for peculiar purposes, so the content of the mud can differ depending on the client's needs.
We have invented an innovative technology for drilling muds production: a Vortex Layer Device – AVS. All chemical and physical reactions are intensifying in AVS. Due to its technology mud won’t flake and the jelly effect will work better.
Mud made in our device has higher hole cleaning efficiency, a higher rate of penetration, and lower mechanical specific energy.
All components are homogenizing during one stage and you can add them all at once. You won’t need any additional equipment for the mixing. Just the tanks and pumps you already have.
AVS has shown great performance on this process and our device is patented.

Catfish is a freshwater fish that is now selling well. It is also very simple in the usual breeding. As long as choose a place with good water source, freshwater, no industrial pollution, good soil quality, and convenient transportation. The bottom of the pool is flat, the pond base is strong, the water retention performance is good, and there is no high damper in the surrounding air. After nuisance treatment, it should be properly placed at the appropriate time. Feeding regularly and quantitatively every day, change the water in time.
Scientific feeding, when selected fish feed pellets, fishermen should choose regular manufacturers to produce quality-assured feed. Fish feed pellets can be made using a fish feed extruder if conditions permit. A small amount of meals helps to promote the digestion and absorption of fish, and 70% of the fish feed pellets are fed during the highest oxygen in the pond during the day. Which is beneficial to digestion and absorption, increase feed conversion rate and reduce feed cost.
Advantage of floating fish feed pellet
1.In the processing of making pellet, high temperature and high pressure can kill germ, eggs, fungi and so on, then adding a mount of drug in the raw material can prevent and cure diseases. Diphenylguanidine, keqiu powder can against coccidiosis, Antibiotics such as oxytetracycline can improve immunity, preventing diarrhea.
2.Feed particles, made by high temperature and high pressure, can increase the hardness of feed, extending floating time.
3.Because the food material is adequate mixed in the process, during the hot and humid season, if placed a long time, the pellets won’t be fermented sour. Nutritional components adequately intake without waste.
4.Short period of high temperature and high pressure in the processing can cause some changes in nutrients, when the feed goes ripening, some paste and glycation will produce, and taking out fragrance to improve palatability, it is easy to digest.
5.Fish feed pellet machine full use of feed resources, reducing costs. Due to the harvest feed ingredients have a certain seasonality, and feed prices are not the same at different times, so when prepare of feed formulation, to meet the nutritional needs, try best to select of low-cost raw material making pellets, and a variety of materials will make nutritional be balanced.
Suitable Raw Materials: plant protein such as soyabean flour, wheat flour, corn flour and rice flour; animal protein such as crab meal, meat meal, bone meal, shrimp meal and fish meal; and manty other kinds of fish food raw materials.You can also add various ingredients according to local fish living requirement.
Press straw into cattle and sheep feed through feed pellet machine, which is a popular method in recent years. The emergence of the grass pellet machine has realized the reuse of straw. In a sense, it is an environment friendly equipment. Te world have abundant grass resources. If they are used effectively, they can not only solve the problem of grass straw, but also increase income for farmers and improve the rural environment.
The grass pellet machine press crushed stalks and grass into pellets. This kind of pellets can be used as feed for cattle and sheep and used in livestock breeding.
The feed pellet machine can not only compress corn stalks, but also various feed materials such as corn, bran, soybean meal, and cotton meal. Therefore, farmer can use these raw materials with reasonably matched and pressed into nutrient-rich pellet feed for cattle and sheep. Moreover, no additives are needed in the pressing process of pellet feed. The pellet feed will experience high temperature during pressing, which will kill a lot of bacteria, and will make the pellets appear semi-cooked state, which makes them taste natural and sweet.
Many farm owner have started to make their own feed. Using the raw materials around farm, They can combine with his own actual situation, suppresses the feed that belongs to his own poultry and livestock. This is the special feature of the feed pellet machine.
How much does the feed pellet machine price ?
There are several factors related to the feed pellet machine. That is output and power. Each machine has its power and output. Feed pellet machine manufacturers provide a variety of models of pellet machines, and the output of each model is different. Since the output is different, the power is also different, and the price is naturally different. This point needs to be clearly understood by everyone.
The large output of the grass pellet machine can reach 1200kgs per hour, and there are various engine types such as electric motor, diesel engine and gasoline engine. When each user chooses his own feed pellet machine according to his own situation. And provide a variety of pellet machine grinding disc aperture, 2.5-10mm are available, a variety of grinding disc aperture settings, which means that a variety of different diameter particles can be compressed, suitable for a variety of livestock.
Corn stalks and grass are made into feed for cattle and sheep, which reduces the phenomenon of human and livestock competing for food, and enables the rational use of corn stalks. The feed pellet machine has become a new type of environmental protection equipment. People also use pellet machines to press straw into pellet fuel for use. This fuel is pollution-free and is a clean energy source. In short,the pellet machine has great market in the future.
And then, there was hydrogen. Soon after the universe was formed through the Big Bang, the vast expanse of heat that sent time and space hurtling in infinite directions started to cool down. When this happened, the first nuclei began capturing electrons, forming the first two elements: hydrogen and helium. The lightest of all the gases, hydrogen is the first element in the periodic table – with only one proton and one electron – and the most abundant element in the universe. High school textbook facts aside, hydrogen is now a word buzzing with charisma in the energy industry as it could be the answer to decarbonising the world’s industries and spearheading a renewable future.
A quick primer on hydrogen. Current global demand stands at about 75 million metric tonnes, more than three times higher than equivalent consumption in 1975. About 40 million tonnes, or 53%, of this hydrogen is used in oil and natural gas refining – in processes such as hydrocracking or hydrotreating – while most of the remainder is used in the fertiliser industry to produce ammonia. Only a scant amount – 0.5% - is used in other applications.
But it isn’t about where hydrogen has been, but where it could go that has the world – energy and otherwise – excited. Over the past decade, many leading nation have started policies researching and supporting investment in hydrogen technologies, with at least 50 targets, mandates and policy incentives in place, and more arriving. There is a North-South divide in this, since hydrogen technology is being pursued by the likes of the European Union and Japan in their quest for a low or net-zero carbon future, while hydrogen is not mentioned at all in the most recent energy plans of countries such as Indonesia, Thailand, Pakistan or Nigeria. But the potential for hydrogen are a low-carbon replacement for heavy-carbon sources such as coal and fossil fuels is vast. In industry, where most of today’s hydrogen is used, hydrogen could increasingly be used in methanol and steel production, replacing the pollutant-heavy coal that coal, for example, plays in steel-making. In transport, hydrogen fuel cells are the future of road transportation, with alternatives also being developed for aviation and shipping. Hydrogen could also be blended in with existing natural gas networks without any major change in infrastructure for heating and cooling, while hydrogen-linked battery technologies are also the leading options for storing renewable energy from sources such as solar and wind farms. It could also be directly burnt in gas turbines as power generation; or more accurately, hydrogen-based ammonia could plan that role. With all these options in place – and the government backing to make it happen – it is not inconceivable that hydrogen demand could triple again over the next 30 years to over 200 million tonnes by 2050.
The problem is supply. Hydrogen is almost entirely supplied through fossil fuels, with an estimated 6% of global natural gas and 2% of coal dedicated solely to hydrogen production. So while hydrogen can be the replacement for carbon-intensive industries and fuels, the production of it is already carbon-heavy, with hydrogen production releasing some 830 million tonnes of carbon dioxide annually, more than the UK and Indonesia combined. Renewable hydrogen production is possible – mainly through water electrolysis – but infrastructure is scant because costs can be three times higher. This is why it is much cheaper to produce hydrogen in regions like the Middle East, Russia and North America - because natural gas is the largest component of production cost at between 45-75% - while the likes of Japan, China, India and South Korea have to import expensive natural gas to make even more expensive hydrogen.
Which is why the world is now no longer just talking about hydrogen, but an entire rainbow of hydrogen colours. There is brown hydrogen – directly extracted from coal using gasification. Then there is white hydrogen that is a by-product of industrial processes or black/grey hydrogen that is produced from natural gas using steam-methane reforming. Yellow hydrogen is produced through solar grid electricity via electrolysis while pink/red/purple hydrogen is a carbon-free option created through nuclear power that is politically-unfriendly. But the colours that are getting everyone the most excited are in the green-blue spectrum: turquoise hydrogen produced through the thermal splitting of methane that leaves solid carbon rather than carbon dioxide as a by-product; green hydrogen formed through water electrolysis with zero carbon emissions; and then blue hydrogen that is conventional black/grey or brown hydrogen but with all carbon dioxide emitted sequestered through Carbon Capture and Storage (CCS) technology.
The ideal solution is green hydrogen, but costs and infrastructure may prevent this from ever being the only solution. The same caveat applies to turquoise hydrogen. Like it or not, blue hydrogen – which the probably the cheapest of the low/zero-carbon solutions but has opposition from certain quarters – will still play a major role in satisfying future hydrogen demand, which in itself should start a virtuous loop of reducing carbon emissions in industries where hydrogen as a fuel can take hold. The world’s leading energy supermajors and majors are already preparing for this. BP has announced plans to build the largest blue hydrogen production facility in the UK by 2030, while the US climate envoy for the Biden administration John Kerry is calling on the US oil and gas industry to embrace ‘huge opportunities’ in hydrogen. Shell has invested in a tech start-up developing a hydrogen-based zero-emissions aviation engine, while even state oil firms are making moves: Malaysia’s Petronas is expanding its investment into green and blue hydrogen along with advanced CCS projects, while the ever-vigilant Equinor is already part of the EU’s largest green hydrogen project that expects to have 10 GW of capacity by 2040 using renewable offshore wind farms. Crude oil giant Saudi Arabia has plans to become the world’s largest hydrogen exporter through a combination of blue hydrogen from its natural gas reserves and green/yellow hydrogen from solar power plants being built at the city of Neom along the Red Sea by 2025. And Hyundai Oilbank has a unique solution as well: it has signed up to import LPG from Saudi Aramco and convert that into blue hydrogen onsite at its Daesan refinery complex in South Korea’s Seosan province, which could be a model that proves that clean hydrogen does not necessarily have to be produced where the source fuel originates to make the best commercial sense.
If the buzzword for the 2000s and 2010s in the energy industry were LNG and shale, respectively, then the buzzword for the 2020s is likely to be hydrogen. Too many moves are being made by governments and too many investments approved by industry titans for this to be ignored. After all, a net-zero world will benefit everyone. And it seems that the first ever element to be create in this universe is the key to creating that future.
